High-Field-Blinded Assessment of Portable Ultra-Low-Field Brain MRI for Multiple Sclerosis.

Background And Purpose: MRI is crucial for multiple sclerosis (MS), but the relative value of portable ultra-low field MRI (pULF-MRI), a technology that holds promise for extending access to MRI, is unknown. We assessed white matter lesion (WML) detection on pULF-MRI compared to high-field MRI (HF-MRI), focusing on blinded assessments, assessor self-training, and multiplanar acquisitions.

Methods: Fifty-five adults with MS underwent pULF-MRI following their HF-MRI.

Derivation and validation of a clinical predictive model for longer duration diarrhea among pediatric patients in Kenya using machine learning algorithms.

Background: Despite the adverse health outcomes associated with longer duration diarrhea (LDD), there are currently no clinical decision tools for timely identification and better management of children with increased risk. This study utilizes machine learning (ML) to derive and validate a predictive model for LDD among children presenting with diarrhea to health facilities.

Methods: LDD was defined as a diarrhea episode lasting ≥ 7 days.

Super-photostable organic dye for long-term live-cell single-protein imaging.

Organic dyes play a crucial role in live-cell imaging because of their advantageous properties, such as photostability and high brightness. Here we introduce a super-photostable and bright organic dye, Phoenix Fluor 555 (PF555), which exhibits an order-of-magnitude longer photobleaching lifetime than conventional organic dyes without the requirement of any anti-photobleaching additives. PF555 is an asymmetric cyanine structure in which, on one side, the indole in the conventional Cyanine-3 is substituted with 3-oxo-quinoline.

Spatiotemporal imaging of nonlinear optics in van der Waals waveguides.

Van der Waals (vdW) semiconductors have emerged as promising platforms for efficient nonlinear optical conversion, including harmonic and entangled photon generation. Although major efforts are devoted to integrating vdW materials in nanoscale waveguides for miniaturization, the realization of efficient, phase-matched conversion in these platforms remains challenging. Here, to address this challenge, we report a far-field ultrafast imaging method to track the propagation of both fundamental and harmonic waves within vdW waveguides with femtosecond and sub-50 nanometre spatiotemporal precision.

Practices and perspectives of genetic counselors about high-risk pancreatic cancer screening: A cross-sectional survey study.

Surveillance of individuals at high-risk of pancreatic cancer using CAPS criteria and other expert consensus guidelines may result in earlier pancreatic cancer detection in some cases; therefore, clinicians are responsible for appropriately identifying and referring these individuals to appropriate high-risk pancreas cancer screening programs. This study aimed at assessing the perspective, knowledge, and clinical practices of cancer genetic counselors surveyed nationwide towards identification of individuals at high-risk of pancreatic cancer and utilization of high-risk pancreatic cancer screening programs. One hundred and eighty-nine genetic counselors who listed "Cancer" as their specialty on the NSGC website responded to the survey, which consisted of multiple practice-based, knowledge-based, and clinical vignette-based questions.

Can large language models fully automate or partially assist paper selection in systematic reviews?

Background/aims: Large language models (LLMs) have substantial potential to enhance the efficiency of academic research. The accuracy and performance of LLMs in a systematic review, a core part of evidence building, has yet to be studied in detail.

Methods: We introduced two LLM-based approaches of systematic review: an LLM-enabled fully automated approach (LLM-FA) utilising three different GPT-4 plugins (Consensus GPT, Scholar GPT and GPT web browsing modes) and an LLM-facilitated semi-automated approach (LLM-SA) using GPT4's Application Programming Interface (API).

Association between patient perception of disease status and different components of the Minimal Disease Activity (MDA) criteria in psoriatic arthritis.

Objective: The aim of this analysis was to evaluate the relationship between the criteria met of the Minimal Disease Activity (MDA) score for psoriatic arthritis (PsA) and patient-perceived disease status.

Methods: We analysed data from the ReFlaP study (NCT03119805), a cross-sectional international study of adult patients with PsA. Patients self-reported if they felt their PsA was in remission (REM), low disease activity (LDA) or neither.

Objectives: To explore the effects of long-term exposure to PM and its constituents on visual impairment.

The polypharmacy combination of the BCL-2 inhibitor venetoclax (VEN) and the FLT3 inhibitor gilteritinib (GIL) is more active in acute myeloid leukemia cells than novel polypharmacologic BCL-2/FLT3 VEN-GIL hybrid single-molecule inhibitors.

Current treatments for acute myeloid leukemias (AMLs) cure fewer than 30 % of patients. This low efficacy is due, in part, to the inter-patient and intra-patient heterogeneity of AMLs; accordingly, all current AML treatment regimens involve drug combinations (polypharmacy). A recently-completed clinical trial in relapsed/refractory AML using a combination of two newer targeted antileukemics, the BCL-2 inhibitor venetoclax (VEN) plus the FLT3 inhibitor gilteritinib (GIL), yielded highly promising results for this two-drug polypharmacy combination.

A phase 1 trial of prizloncabtagene autoleucel, a CD19/CD20 CAR T-cell therapy for relapsed/refractory B-cell non-Hodgkin lymphoma.

Prizloncabtagene autoleucel (prizlon-cel), a novel bispecific chimeric antigen receptor (CAR) T-cell, targets and eliminates CD19/CD20 positive tumor cells. This phase 1, open-label study investigated the safety and efficacy of prizlon-cel in patients with relapsed/refractory B-cell non-Hodgkin Lymphoma (r/r B-NHL). Patients with CD19 and/or CD20-positive r/r B-NHL received a 3-day lymphodepletion (cyclophosphamide: 300 mg/m2/d; fludarabine: 30 mg/m2/d) followed by an intravenous dose of prizlon-cel.

Preserving the Academic Mission Amid Radiologist Shortages and Financial Pressures.

Academic radiology practices are navigating unprecedented operational and financial challenges, including a growing radiologist shortage, escalating imaging volumes, and mounting financial pressures driven by rising salaries, increasing practice expenses, and declining reimbursements. To address these challenges, academic department leaders must prioritize securing enhanced hospital professional service agreements and renegotiating outpatient imaging agreements. These strategic initiatives are essential to sustaining academic missions and ensuring long-term success.

Damage control resuscitation: how it's done and where we can improve. A view of the Brazilian reality according to trauma professionals.

Introduction: Hemorrhage is the leading cause of preventable deaths in trauma patients, resulting in 1.5 million deaths annually worldwide. Traditional trauma assessment follows the ABC (airway, breathing, circulation) sequence; evidence suggests the CAB (circulation, airway, breathing) approach to maintain perfusion and prevent hypotension.

Defining the Cost of Arthroscopic Rotator Cuff Repair: A Multicenter, Time-Driven Activity-Based Costing and Cost Optimization Investigation.

Background: Rotator cuff repair (RCR) is a frequently performed outpatient orthopaedic surgery, with substantial financial implications for health-care systems. Time-driven activity-based costing (TDABC) is a method for nuanced cost analysis and is a valuable tool for strategic health-care decision-making. The aim of this study was to apply the TDABC methodology to RCR procedures to identify specific avenues to optimize cost-efficiency within the health-care system in 2 critical areas: (1) the reduction of variability in the episode duration, and (2) the standardization of suture anchor acquisition costs.

MmuPV1 infection of Tmc6/Ever1 or Tmc8/Ever2 deficient FVB mice as a model of βHPV in typical epidermodysplasia verruciformis.

Typical epidermodysplasia verruciformis (EV) is a rare, autosomal recessive disorder characterized by an unusual susceptibility to infection with specific skin-trophic types of human papillomavirus, principally betapapillomaviruses, and a propensity for developing malignant skin tumors in sun exposed regions. Its etiology reflects biallelic loss-of-function mutations in TMC6 (EVER1), TMC8 (EVER2) or CIB1. A TMC6-TMC8-CIB1 protein complex in the endoplasmic reticulum is hypothesized to be a restriction factor in keratinocytes for βHPV infection.

Using internet-assisted geocoding of 1940 census addresses to reconstruct enumeration districts for use with redlining and longitudinal health datasets.

Many historical administrative documents, such as the 1940 census, have been digitized and thus could be merged with geographic data. Merged data could reveal social determinants of health, health and social policy milieu, life course events, and selection effects otherwise masked in longitudinal datasets. However, most exact boundaries of 1940 census enumeration districts have not yet been georeferenced.
